10.3.1. Types of Emulsions

Try these first

1. 1.

   Define bituminous emulsions.

   Hint

   Think about the materials involved.

2. 2.

   What is the primary difference between cationic and anionic emulsions?

   Hint

   Consider their electrical charges.

3. 3.

   What type of emulsion is preferred for strong bonding with aggregates?

   • Cationic Emulsions
   • Anionic Emulsions
   • Neither

   Hint

   Think about their ionic charges.

4. 4.

   True or False: Anionic emulsions are more commonly used than cationic emulsions.

   • True
   • False

   Hint

   Recall the definitions from class.

5. 5.

   You are tasked with a road construction project in a humid region where acidic aggregates are prevalent. Would you choose cationic or anionic emulsion, and explain your rationale.

   Hint

   Think about the adhesion properties discussed.

6. 6.

   A contractor incorrectly used a slow-setting emulsion in a high-traffic area during summer. Analyze the potential consequences of this decision.

   Hint

   Consider how temperature affects the curing process.
